Displays are a common feature in our modern digital world, found in devices ranging from phones and tablets to computer monitors and TVs. As the demand for consumer electronics continues to rise, so does the impact on the environment. It is estimated that over 1 billion smartphones were sold just last year. However, traditional screen technology comes with significant environmental consequences, from the manufacturing of components to disposal issues related to hazardous materials like mercury and lead. As the market for electronic devices shows no signs of slowing down, it is crucial to explore sustainable innovations.
Rajeev Singh, MD of BenQ India and South Asia, points out that there are promising eco-friendly technologies emerging, such as e-paper displays made from biodegradable organic components that only consume power during screen refreshes. Reflective ABI micro-electrical-mechanical systems utilize ambient light instead of power-hungry backlighting engines. Recyclable solar-cell LCD alternatives also show potential for sustainability. Advances in materials science, particularly in semiconductor purity, may lead to efficiency improvements in nano-crystal LEDs.
Besides hardware, Singh emphasizes the importance of power-optimized software and firmware design, as well as user settings like automatic brightness adjustment, in reducing energy consumption. He stresses the need for an eco-friendly approach throughout the entire value chain, with manufacturers playing a key role by integrating recycled resins and implementing takeback initiatives to reuse materials.
Discussing technological trends, Singh mentions displays utilizing next-gen semiconductors for increased efficiency, but notes challenges in production scale and integration. He highlights the potential of cellulose nanofibers for transparent, flexible, and biodegradable films, as well as advancements in manufacturing making integration economically feasible for displays and electronics. He also mentions emerging features focused on eye care and health, such as blue light filters and ergonomic design elements.
However, Singh acknowledges that environmental best practices may have trade-offs, particularly with the resource and energy demands of high-performance semiconductors. He emphasizes the need for transparency in marketing products as ‘eco-friendly’ and the importance of sustainable production and consumption policies to address environmental impacts effectively.
In conclusion, Singh underscores the importance of collaboration and industry standards to drive positive transformations in the display sector. He believes that India has a critical opportunity to promote greener technologies through policy interventions, collaborative actions, and market forces to prevent environmental degradation and foster sustainable industry practices.
